Primary myectomy for sarcoma.

A Rydholm, B Rööser, B M Persson

    Summary
    This summary is machine-generated.

    En bloc myectomy without open biopsy is effective for high-grade soft-tissue sarcomas. This approach, preserving the anatomical compartment, showed a low local recurrence rate in a seven-year follow-up study.

    Area of Science:

    • Orthopedic Oncology
    • Surgical Oncology
    • Musculoskeletal Tumors

    Background:

    • High-grade soft-tissue sarcomas require effective surgical management to minimize recurrence.
    • Traditional surgical approaches often involve wide compartmental resection, which can lead to significant morbidity.

    Purpose of the Study:

    • To evaluate the efficacy of en bloc myectomy without open biopsy for high-grade soft-tissue sarcomas.
    • To determine if preserving the anatomical compartment is oncologically safe for these tumors.

    Main Methods:

    • Sixteen patients with high-grade Stage-IIA soft-tissue sarcomas underwent en bloc myectomy of affected muscles.
    • Tumors were removed without preoperative or intraoperative open biopsy, preserving deep fascia and intermuscular septa.
    • Fine-needle aspiration confirmed sarcoma diagnosis in eleven patients; follow-up was a median of seven years.

    Main Results:

    • Only one local recurrence was observed among the sixteen patients.
    • The median follow-up was seven years (range, one to fourteen years).
    • No adjunctive therapies were administered post-surgery.

    Conclusions:

    • En bloc myectomy, respecting fascial barriers, is a viable and effective treatment for high-grade soft-tissue sarcomas.
    • Total compartmental resection may not be necessary for high-grade sarcomas when proper indications and surgical techniques are followed.
    • Uninvolved muscle fascia can act as an adequate barrier against tumor spread, preventing skip metastases.
